Answer: 33 = d
Step-by-step explanation: To solve for d in this equation, we want to get d by itself on the left side of the equation.
Since 6 is being subtracted from d, to get d by itself, we need to add 6 to the right side of the equation. If we add 6 to the right side of the equation, we must also add 6 to the right side of the equation.
Notice that on the right side, -6 and +6 cancel each other out so we're simply left with d. On the left side, 27 + 6 = 33 so we have 33 = d or d = 33. Both answers will work.
